Abstract: | A new type of sensor with the flexible substrate is introduced. It is applicable in measuring instantaneous heat flux on the
model surface in a hypersonic shock tunnel. The working principle, structure and manufacture process of the sensor are presented.
The substrate thickness and the dynamic response parameter of the sensor are calculated. Because this sensor was successfully
used in measuring the instantaneous heat flux on the surface of a flat plate in a detonation-driven shock tunnel, it may be
effective in measuring instantaneous heat flux on the model surface. |
